MCP2544FDT-E/SNVAO

Drivers, Receivers, Transceivers Overview

The MCP2544FDT-E/SNVAO is a CAN FD transceiver from the MCP2542FD/4FD family, designed for high-speed communication up to 8 Mbps. It operates within a VDD supply range of 4.5V to 5.5V and supports an extended temperature range of -40°C to +125°C. The device features one driver and one receiver with a maximum propagation delay of 120 ns and loop delay symmetry of -10%/+10% at 2 Mbps. It provides ESD protection on CANH and CANL pins meeting IEC61000-4-2 standards up to ±13 kV. The component utilizes an 8-Lead SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Supports CAN 2.0 and CAN FD physical layer requirements with optimized performance for data rates up to 8 Mbps.
• Includes automatic thermal shutdown protection and permanent dominant detection to prevent bus corruption.
• Ensures CAN bus isolation by disconnecting CANH and CANL pins when the device is unpowered.
• Meets stringent automotive design requirements including conducted emissions and direct power injection tests.

Drivers, Receivers, Transceivers Applications

• CAN 2.0 and CAN FD networks in automotive applications
• Industrial control systems requiring high-speed communication
• Aerospace and medical equipment interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's Product Identification System to confirm package type and temperature grade. Ensure compatibility with the target microcontroller's I/O voltage levels, as this variant lacks a separate VIO pin. Confirm that the application environment remains within the specified operating temperature range of -40°C to +125°C for reliable operation.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a CAN FD transceiver without a dedicated VIO pin is required, as the digital I/O supply is internally connected to VDD. This model is suitable for designs where the microcontroller interface voltage matches the system supply voltage. Consider the 8-Lead SOIC package for standard PCB layouts. Verify if Wake-up Pattern (WUP) functionality is needed, as this specific part does not support it compared to the WFD variants.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MCP2542FD/4FD and MCP2542WFD/4WFD family manufactured by Microchip Technology. The family includes variants with and without Wake-up Pattern capabilities and different package options such as DFN and TDFN. The MCP2544 series specifically integrates the digital I/O supply internally, distinguishing it from the MCP2542 series which offers a separate VIO pin for flexible logic level interfacing.

Drivers, Receivers, Transceivers Replacement Considerations

The MCP2542FD serves as a functional alternative but includes a separate VIO pin, requiring circuit adjustments for I/O supply routing. The MCP2542WFD adds Wake-up Pattern capability, which may be unnecessary or require configuration changes. Ensure any replacement maintains the same SOIC-8 package and meets the 8 Mbps data rate requirement.
